Data Engineering is responsible for the development and delivery of our most important asset—our data. With thousands of data sources from around the world, the team ensures that data is accurate, normalized, and delivered at a velocity that keeps up with real-world changes. As we expand our markets and the scope of data we provide to our customers, our team must scale to meet that demand.
As a Staff Data Engineer on the Data Lake team at H1, you will play a critical role in shaping the architecture, scalability, reliability, and long-term direction of our core data platform. This role is designed for a highly technical engineer who is excited to grow into an Engineering Manager track while remaining deeply hands-on technically.
The Data Lake is the foundation of H1’s platform, responsible for the validation, accuracy, standardization, and quality of the data powering every downstream product and team across the organization. You will help lead the evolution of this platform while supporting and mentoring a growing team of engineers.
